Driver fatigue is a leading cause of vehicular accidents (Lee, 2006). Additionally, development of newer technology such as vehicle automation offers a potential countermeasure to driver fatigue. As vehicle operation becomes increasingly automated, driver fatigue appears to be a pressing safety issue. A number of countermeasures have been evaluated in the attempt to alleviate driver fatigue. In the present context trivia games have been suggested as a fatigue countermeasure but like cell phone use, they may prove distracting. The present study investigated the effects of two especially relevant workload factors on driver performance: automated driving and secondary media usage. Vehicle automation is a relatively new trend among automakers that can potentially alleviate the adverse effects of fatigue and in turn regulate workload, however recent studies have suggested that automation may result in a dangerous state of underload in which effort is withdrawn from the driving task (Desmond, Hancock & Monette, 1998; Funke et al., 2005). A manipulation of full and partial vehicle automation was used to induce fatigue during simulated driving. Participants were also assigned to one of three media device conditions (control, cell phone or trivia). Subjective state response, vehicle control and reaction time to a sudden event were recorded. As predicted, the media devices did help minimize the loss of task engagement and elevated distress produced by vehicle automation. We also extended findings that the media devices helped improve concurrent driver performance, with control driving shown to be associated with the worst vehicle control. However, media usage was not associated with faster response time to subsequent “sudden events”, suggesting that such devices may not enhance alertness during unpredictable events.
